Amino acid sequence of beta-galactosidase. XI. Peptide ordering procedures and the complete sequence.

A V Fowler, I Zabin.   

Abstract

The amino acid sequence of beta-galactosidase has been determined. The monomer contains 1,021 amino acid residues in a single polypeptide chain and has a molecular weight of 116,349. All 80 tryptic peptides as well as all 24 CNBr peptides have been isolated in pure form. Evidence is presented for the ordering of the CNBr peptides. The sequence determination was aided by analysis of cyanogen bromide peptides obtained from a polypeptide fragment produced by a lacZ termination mutant strain.
